What is the Commercetools + Sizebay integration

Fashion returns hurt twice – you lose margin on reverse logistics, and you lose trust when customers guess their size and still get it wrong. The problem usually starts on the PDP: size charts are inconsistent, fit notes live in PDFs, and customer support ends up explaining basics that should be clear at checkout. The commercetools Sizebay integration connects Sizebay size recommendation and virtual try-on to your commercetools catalog and PDP experience, so fit guidance is driven by product-level sizing data instead of generic rules. It turns sizing into a measurable part of your storefront flow, while keeping product data ownership in commercetools and letting Sizebay do what it does best where it matters most – in the moment the customer chooses a size. This setup fits if you sell apparel, footwear, or accessories and want a commercetools size recommendation integration that scales across many SKUs and brands.

Protect brand trust by reducing “wrong size” disappointment on delivery

How the Commercetools Sizebay integration works technically

• Product identifiers (SKU, product key, variant ID) are mapped between commercetools and Sizebay to keep recommendations tied to the correct variant on the PDP. 

• Size-related attributes and fit content (measurements, size tables, fit notes, and gender or category cues) are synchronized to Sizebay as product-level sizing data, with locale handling where available. 

• Storefront requests pass the current product, variant, and shopper inputs to Sizebay, and the response returns recommended size and try-on payloads for rendering on PDP components. 

• Delta-based updates send only changed product and attribute records to reduce load, with full exports used for initial alignment or major catalog changes. 

• Sync jobs validate required mappings and log rejected records (missing SKUs, unsupported attribute formats, and duplicate identifiers) for reconciliation. 

• Event-driven triggers can react to product publish, unpublish, and variant changes in commercetools to keep Sizebay content aligned with live catalog state.
